Application and. my a, 1919. Serial No. 294,421.

A particularly valuable advantage. at-

tained'by my present improvements consists in the adaptability of mymechanism to the piercing of fabrics, soft leather or like yieldingmaterial, where 1t 18 desirable to retain the full strength of thematerial and'to avoid cutting or damagingth fib e thereof.

. My improvements may desirably be embodied in the class of punching andeyeleting machines described in prior Patent $51,120,989, dated December15th, 1914:, wherein the punch and set are arranged permanently to be inaxial alinement and in which a support is moved beneath the punch andset to insert an eyeletin the ma terial,'the actuating members in myimproved machine being substantially the same. I

Important features of my invention coniprise means for piercing thematerial with a pointed punch, means for supportingthe material whilebeing pierced, and means for retaining the eyelet to the punch until thesetting-of the same in the material is completed.

The described and other features ofmy inventionare illustrated intheaccompanying drawings wherein like reference characters are applied tothe corresponding parts in the several views. I

14L is a side elevation of a complete machine, showing meansforoperating the several members: some parts'being' shown broken away, andsome in section.

The operating parts of these-improvements are mounted upon a supportingframe a upon which is slida'bly mounted the plate The/frame (1)isrecessed to receive the anvil (3) and the plate (2) is provided with aclearance recess (a and channeled to receive the 'slidable supportjaws(5,, 5) which are retained in their Leaf springs (7,7) fastened to theplate (2) compress j the supportjaws (5,5) together.' The supportingjaws (5,5)- are shaped on their abutting ends to conform to the shape ofthe punch which is slidably located within the set (9).- The punch (8)is formed to receive an expanding spring (10) whichis provided withlipsadapted to retain an eye-- let on the punch when in expanded positionand release it when compressed. r a

I Referring now to 14:, wherein there is l i illustrated means foractuating the described members in their operations as follows: Motionmay be imparted to the pulley 13, which is adapted to engage with androtate the shaft 14, upon which is secured the disk 15, which is groovedon its sides with the cam tracks 16, and 17.

The punch 8, is secured to the punchplunger 18, which is connected bythe studs 19 and the connecting link 20, to the lever 21.

The lever 21 is pivotally mounted at 22 upon the frame 1, and isprovided at one end with a roller 23, which engages with the cam track16, formed in the disk 15, which when rotated imparts the aforedescribed movements to the punch 8.

The set 9 is secured to the set-plunger 2% which is connected by thestuds 25 and the links 26 to the lever 27.

Thelever 27 is also pivotally mounted at 22 upon the frame 1, and isprovided at one end with a roller 28 which engages with the cam track17, formed in the disc 15, which when rotated imparts the aforedescribed movements to the set 9.

.Upon the shaft 14 is secured a disk 30 having a crank stud 31, whichengages with a cam slot 32- formed in an arm 33 which mav be pivotallymountedupon a stud 34 erected on the frame 1.

Upon the slide 2 is erected the stud 35, which engages a link 36connected to the arm 33 by a stud 37. Thus when the disk 30 with thecrank stud 31 is rotated, the crank stud 31 moving in the cam slot 32 isadapted to rock the arm '33, and by means of its connecting link movethe slide 2 with the supporting jaws 5 to or from beneath the materialbeing operated upon.

The operation of the described mechanism in piercing a hole in thematerial and setting an eyelet, or like article therein is as follows:

The material supporting jaws (5, 5) being in alinement with the punch(8) and set (9) the material is placed thereover, an eyelet is impaledon the punch (8) and with the punch and set (9) positioned relative as 1shown in Fig. 2 the punch operates to pierce the material and the setthen further de scends to push the eyelet through the material into theposition shown in Fig. i.

The punch (8) andset (9) are now elevated sufiiciently to remove anypressure on the eyelet and the material and the plate (2) with thesupporting jaws (5, 5') is withdrawn from under the material, the jaws('5, 5) yielding from the eyelet, thus bringing the anvil (3) intoco-acting relation with the punch (8) andset (9) which are now broughtdown respectively to guide and set the eyelet to the material-as shownin Fig. 5.

- The retaining spring (10) in this position from the material, thudcompleteing the operation.

It will be noticed that the jaws (5, 5) are so formed as to support thematerial at the entrance of the point of the punch. and by yieldinglaterally continue such support throughout the operation of piercing thematerial.

A form of punch particularly adapted to pierce material is shown in Fig.11. A further advantage of this form of punch is that in piercingmaterial over a simple supporting member as shown in Fig. 6, thematerial is apt to wedge and remain therein unless the punch is groovedas shown, the groove acting to free the material from the supportingplate 6.

While I have shown and described an approved embodiment of the featuresof'niy present invention, it. will be understood that many modificationsof the various features thereof may be made without departing from thescope of mv invention. For instance, as will be understood. the piercingyielding jaws 5) will cooperate with the eyelet and are suitably formedwith inclined abutting faces (11, 11) so that the engagement therewithof the eyelet will cause the jaws to yield in the manner heretoforedescribed.

it is therefore intended that all matters herein contained shall beinterpreted as illustrative and not in a limiting sense.
